Dana White would never say never to a boxing vs. MMA showdown starring Wladimir Klitschko and Junior dos Santos – he just doesn’t want to see it.

“I wouldn’t want to put Junior in there to do that,” White said at a pre-event news conference for the Brazilian’s rubber match against champ Cain Velasquez at UFC 166, which takes place tonight at Houston’s Toyota Center.

That, in White’s view, is fighting in the clinch-heavy style that’s kept the 37-year-old Klitschko on top of heavyweight boxing along with his older brother, Vitali. Earlier this month, the younger Klitschko defended his titles for the fifth time, stifling Alexander Povetkin en route to a unanimous decision.

White called the fight “the most disgusting, embarrassing thing” and said Klitschko should have been disqualified for his actions in the ring. The UFC president even got up from his chair on the press conference stage and demonstrated what he believed were flagrant rule violations in the boxing title bout.

But more than skirting a fair fight, White believes Klitschko is doing no less than draining the excitement out of boxing. He said the few fights he’s seen from the champ have made him sick.

“That’s the heavyweight champion of the world,” he said. “When (Mike) Tyson was in there, heavyweight matches were exciting. I don’t know who wants to watch that s–t. I watched it, and it’s literally embarrassing. [The Klitschkos] are an embarrassment to the sport of boxing.”

And yet dos Santos (16-2 MMA, 10-1 UFC), who’s a slight underdog to retake the UFC title he lost this past year to Velasquez (12-1 MMA, 10-1 UFC), is the latest MMA notable to express interest in testing his fistic skills against boxing’s best.

“I think if they give me four months to get prepared, I can beat [the Klitschkos]” he told MMAFighting.com. “I love to train boxing and I think I have enough skills in boxing. I know how to see a good fight. Four months – that’s what I need.”

But ample preparation is the last thing White thinks about when he envisions a bout between the two.

“First of all, I saw the Klitchsko brothers in Los Angeles one time,” he said. “They’re f—ing monsters. They’re huge.

“And how are you going to fight a guy that doesn’t want to fight? That guy doesn’t want to fight anybody. He wants to grab you by your f—ing head and lay on you. Literally, to the point where it’s embarrassing, where he runs and grabs on to you. It’s disgusting.”

White is open to seeing boxers test their luck in the UFC. Earlier this year, he challenged Tyson Fury to try his hand in the UFC’s octagon after the trash-talking heavyweight called out Velasquez.

Three years ago, the executive was convinced to give ex-boxing champ James Toney a try in the cage and watched nervously before UFC Hall of Famer Randy Couture submitted him in the first round at UFC 118.

But when it comes to farming his fighters out to the boxing world, White doesn’t feel as generous.

“These guys want to box boxers,” he said. “Boxing is a completely different sport. What I always say is if the boxers want to fight these guys, come on over here. Because what Klitschko does is not fighting. Klitschko doesn’t fight.

“Who knows, maybe Junior dos Santos could go in and knock out Klitschko. [That’s not to say], ‘Absolutely not. It could never happen.’ Anybody could get caught on any given night. I don’t want to see it.”
